Overhead light not working

We have an overhead light in our bedroom that just stopped working. I replaced the bulb and still nothing. There's no blown circuit. How can I figure out what's wrong?

That depends on how handy you are.
It could be a bad switch, or a loose wire somewhere.

1) CAREFULLY check power at the fixture socket.

If no power

2) Check power at the switch.

If you have power at the switch, remove the fixture and check connections.

If you have no power at switch, work your way back thru the circuit and find the fault.

These are basic steps. Installations vary and it would take me longer to go thru every possible step than it would to fix it.

You may also want to very carefully check the lamp socket for electrical power at the tang which makes contact with the spot on the end of the light bulb. These sometimes get bent and make very little contact with a newer bulb when the bulb is replaced. The heat from the bulb will cause the tang to bend which causes loss of contact. Another problem I have seen is the difference in the length of the base of light bulbs between different brands. Sometimes the threaded part of the base will run out of threads when screwed in which causes the tang and the spot of the bulb base to make very little, if any, contact. With the power OFF, I have had to bend the tang out/down just a little to make better contact with the base. I screw in a light bulb until it glows, then one-quarter turn more, to prevent bending the tang. Good Luck, David

WE had one instance where a raccoon had gotten into the guy's attic, and ate thru the wiring feeding his stairwell light. Seems the beastie thought those wires were in his way, so he took care of `em!

So be sure to check for evidence of critters or varmits in your attic as well ....
